Method and apparatus for driving and controlling on-vehicle loads

摘要

In an apparatus for driving and controlling plural on-vehicle electrical loads, an on-vehicle power supply generates power to be supplied the loads each having a priority. A power calculating device calculates a current available amount of the power to be supplied from the power supply, and a priority changing device changes one or more of the priorities on the basis of inputted information about a vehicle condition, the information including conditions of the loads. A command producing device produces a command value indicative of an amount of the power to be supplied to each of the loads by using the priorities. In this case, a sum of the power to be supplied to each load is kept within the available amount of the power to be supplied. A controller controls the power to be distributed to each of the loads on the basis of the command value.
